Abstract
Changes in standards for firestop material have an important impact on production,application,and testing.According to the previous implementation process of standards,in the initial implementation stage of the new standard,especially in the case of large changes,there will always be some insufficient understanding,confusion of understanding,and even misuse of standards,which bring losses to relevant practitioners.In order to make relevant practitioners better understand and correctly use the new standard,this paper further analyzes and interprets the standard:the newly added part with a greater impact includes percent for cable penetration area,percent for pipe penetration area,use sites,multi-component sealing materials,smoke toxicity,air tightness,flushing test performance;the changes of the standard include fire environmental conditions,test temperature conditions,furnace pressure conditions,specimen production,comprehensive judgment criteria.Combined with engineering applications,modern building requirements,smoke prevention and rescue needs,changes in inspection,and correlation with other standards,the paper discusses the production,use,and inspection of products following the guidance of the new standard.关键词
